+Description
+
+The lzlib compression library provides in-memory LZMA compression and
+decompression functions, including integrity checking of the
+uncompressed data. The compressed data format used by the library is the
+lzip format.
+
+The functions and variables forming the interface of the compression
+library are declared in the file lzlib.h. An usage example of the
+library is given in the file main.cc.
+
+Compression/decompression is done by repeteadly calling a couple of
+read/write functions until all the data has been processed by the
+library. This interface is safer and less error prone than the
+traditional zlib interface.
+
+Lzlib will correctly decompress a data stream which is the concatenation
+of two or more compressed data streams. The result is the concatenation
+of the corresponding uncompressed data streams. Integrity testing of
+concatenated compressed data streams is also supported.
+
+All the library functions are thread safe. The library does not install
+any signal handler. The decoder checks the consistency of the compressed
+data, so the library should never crash even in case of corrupted input.
+
+Lzlib implements a simplified version of the LZMA (Lempel-Ziv-Markov
+chain-Algorithm) algorithm. The original LZMA algorithm was designed by
+Igor Pavlov. For a description of the LZMA algorithm, see the Lzip
+manual.
